Core Drilling Machine (rig) From China Professional Manufacturer

coring machine is mainly applied to the core drilling of diamond and alloy, widely used in engineering geological exploration, hydrological well, shallow layer petroleum, natural gas, geothermal and large diameter foundation engineering construction also can be used for the engineering drilling of the dam grouting and tunnel ventilation and drainage. This machine is reasonable in structure, light weight, large capacity, wide application, stable performance, reliability and high degree standardization.
Characters:
——a wide range of spindle (8) and a reasonable speed range with larger torque at low speed (Max. 4200 N/m)
——Double cylinder hydraulic feeding, long stroke, large vertical through-hole diameter(93mm)
——Large drilling capacity. Rope coring drill pipe (71mm diameter) can drill 1000m nominal drilling depth of 1000 meters,   DCDMA to reach 1800 meters
——Light weight, low center of gravity, compact structure, rational layout, convenient maintenance and repair. the host can be decomposed into 10 parts (maximum detachable parts 300 kg), easy to move, especially suitable for mountain areas, mine, tunnel work.
——Hydraulic chuck clamping force. Provided with a hydraulic lock, clamping stability
——Equipped with hydraulic brake system, deep hole drilling, smooth-down-drilling
—— The gear oil pump oil supply, low power consumption, low oil temperature in hydraulic system, stable work. The system is equipped with a hand pump, when the machine is not working is still available hand pump out hole drilling tool.
——Long distance moving vehicles (up to 460 mm), reliable fixation, high speed drilling with good stability.
——The use of vibration meter, long life-span, flexible and reliable operating control.
